What items should be checked before sitting in the cockpit?

Before sitting in the cockpit, ensuring that the drogue switch and safe-arm handle are properly checked is crucial for safety and operational readiness. The drogue switch is responsible for deploying the drogue chute, which assists in separating the aircraft from a catapult during takeoff. If this system is not correctly set or if the safe-arm handle is in the wrong position, it can lead to disastrous consequences, especially during critical phases like takeoff or emergency situations.

Checking these items is part of the pre-flight procedures which are designed to verify that all safety mechanisms are functional and properly configured. This practice helps to prevent accidental deployments and ensures that the pilot is prepared for any required emergency protocols.

While checking your helmet for a proper fit, the fuel gauge, and the accessibility of the ejection seat manual are important, they do not directly relate to the immediate readiness and safety of the aircraft's critical systems during pre-flight operations. The drogue switch and safe-arm handle are specifically vital components that directly impact the safety and effectiveness of the aircraft's operation.
